JOHN C. HUMPHREYS, OF SUTTON, WEST VIRGINIA.

CHURN.

SPECIFICATION forming part of Letters Patent No. 471,337, dated March 22, 1892.

Application filed May 25, 1891.

To all whom it may concern.-

l 3e it known that 1', JOHN C. HUMPHREYS, a citizen of the United States, residing at Sutton, 1n the county of Braxton and State of \Vest Virginia, have invented a new and useful Rotary Churn, of which the following is aspecification.

This invention relates to improvements in chugns of that class known as rotary dashers.

The objects of my invention are to provide a cheap and simple churn easily operated by hand and adapted to convert the cream into butter in a minimum space of time by a thorough manipulation of the globules of cream.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed outrin the claim.

Referring to the drawings, Figure 1. is an elevation of a churn constructed in accordance with my invention. Fig. 2 is a detail in perspective of the dasher and its mechanism. liig. 3 is a vertical section. Fig. 4 is a detail intransverse section through the dasher. Fig. o is a plan of the dasher-operating mechanmm, the master-gear and its su pporting-standard being removed.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates the body of the churn, and the I same may be of any construction or configuration best adapted for the purpose in view, but is in this instance cylindrical. At two diametrically-opposite points recesses 2 are formed in the upper edge of the churn, and in the same are seated the lugs 3, formed on the periphery of a ring-gear 4, said lugs being bolted to position by means of bolts 5, which also pass through the branches 6 of a tripodian standard. This standard has two of its legs connected by transverse bars 7 and at its upper end has formed a bearing 8, in which is mounted the shaft 10, at one end of which is mounted the master-gear 9, and at the opposite side of the bearing said shaft is provided with an operating-crank 11. y

In the transverse bars 7 there is journaled a vertical shaft 12, which between the bars carries a gear 13, the teeth of which are engaged and driven by those of the master-gear.

Serial No. 393,979. (No model.)

Below the lower bar 7 and the cover 14,which latter, it will be observed, is formed in sections, there is rigidly secured to the shaft 12 a pair of triangular plates 15, said plates being spaced apart and occurring opposite the ring-gear 4 and provided at each of their angles with aligning bearings, in which crossshafts 16 are located, and carry small gears 17, the teeth of which are engaged by the teeth of the ring-gear. These shafts extend below the lower triangular plate of the pair and are journaled in the extremities of a triangular rest 18, secured to the lower end of the dashershaft 12. The dasher-shaft 12 is provided with a series of three blades or dashers 19, and each of the short shafts 16 is provided with a series of three blades 20, narrower than the blades 19, at opposite sides of which latter the blades 20 occur.

In operation, motion will be imparted by the master-gear to the shaft 12 through the medium of the gear 13, and the shaft 12 revolving will carry with it the triangular rest, the short shafts l6,their triple blades 20, and the triple blades 19 of the shaft 12. As the blades 19 are moved in one direction by the rotations of the shafts 12 the blades 20 are rapidly rotated in a reverse direction by' reason of their gears 17 engaging with the ringgear, which latter, it will be observed, is stationary. By this means it will be apparent that I have one series of three large dasher blades or paddles revolving in one direction while the series of nine small dasher blades or paddles are moved in an opposite direction. The agitation is so great that the globules of cream are destroyed in an exceedingly short time and the formation of butter rapidly takes place.

Having described my invention, what I claim is- In a churn, the combination, with the stationary internally-toothed ring-gear, the main vertical dasher-staff, and the fixed gear mounted on the upper end of the main dasher-staff, of the upper pair of bearing-plates 15, and the lower rest-plate 18, mounted fixedly upon the main staff, the series of fixed radial blades 19, fixedly mounted on the main staff, the'series of auxiliary dasher-staffs 16, alternating with the blades 19, the auxiliary blades 20, fixedly connected to and radiating from each of the In testimony that I claim the foregoing as staffs 16 and located within the path traversed my own I have hereto afifixed my signature in by the main blades, the latter extending bepresence of two Witnesses.

yond the line of the auxiliary blades, and the JOHN C. I'IUMPI-IREYS. 5 small gears 17, fixed upon the upper ends of Witnesses:

the staffs 1G and engaging the teeth of the E. A. BERRY,

ring-gear, substantially as specified. (J. K. NEWLON.
